摘要The XBL and RBL samples presented recently by Kollgaard et al. (1996) are employed to investigate whether the extended power of BL Lac objects is correlated with the core dominance parameter. The results show that the two quantities are statistically anti-correlated at a rather high level of confidence for both XBLs and RBLs. Since the core dominance parameter is generally used as a relative measure of orientation and the extended emission of radio sources is assumed unbeamed and isotropic, the results obviously contradict common inference from unified schemes. By adopting and combining some basic concepts of unified schemes and the different SED scenario, a possible explanation for the results is suggested.
